Envelope Addressing Question
I am going to do calligraphy for my invites but just the addresses on the outside envelopes not the inside envelopes. But then I noticed the addresses of the people that I am inviting with a 'Guest' and I realized that I cannot address the envelopes to Mr.XXX and Guest but If I don't then how would that person know I am inviting them with a guest? Any suggestions on how to do this?
